Scrape all the specfiles from Fedora for source URLs

[mfocko]

To be able to adjust the firewall rules »beforehand« on the MP+, we need to know the domains/forges from which users are using sources for the sync-release actions.

Scraping the specfiles and configs of current users didn't provide enough benefit, since it can be still a pain point during an onboarding of new users

• scrape all the specfiles
• pinpoint forges/URLs that we do not support as of now
  • (optionally) ask the packagers if they'd be interested in onboarding
  • also check for activity within the packages
• edit comment with the “waiting list” in Firewall rules that need to be enabled deployment#575
• (optionally) open a ticket to adjust the firewall rules
  • (“optional”) ticket per URL :)
• (optionally) verify that the sources can be obtained

I am running:

for i in *spec; do
spectool $i |grep Source
done >/tmp/output.txt

Here is the list of all Sources from Fedora:

• scrape all the specfiles

Maybe we should go also through Packit configs, because (at least in theory) upstream_project_url can be blocked while Source0 URL is fine.
